If you go to Holland, you have GOT to check out Madurodam. Sure it costs an outrageous €15 per adult but it's still fun to visit. The theme park cum war memorial is made up of 1:25 scale miniature versions of the Netherlands. It has been around for a long time and still draws the crowds. A real treat especially for those who are into trains.
They did try to spice things up with a new Sesame Street attraction when I was there but it was just an area with some videos, computers and merchandise to buy.
If you are in a hurry to see all of the Netherlands, I suppose you could come here and do it all in one day.
